The Holiness of God
The Bible says of God, “You are not a God who takes pleasure in wickedness; no evil dwells with You” (Psalm 5:4). What does this mean? It means that God is absolutely holy, free from corruption and sin. “God is Light, and in Him there is no darkness at all” (1 John 1:5b). In other words, God is absolutely pure. This also means that God is a righteous ruler and judge. The Bible says of God, “Righteousness and justice are the foundation of Your throne; lovingkindness and truth go before You” (Psalm 89:14). What we have to conclude from this is that God cannot and will not overlook sin; He will punish the guilty. Just as an earthly judge is deemed good for judging according to the law, so the Judge of the universe judges rightly, according to His holy Law, which has as its basis His own holy nature
The Sinfulness of Man
What we have just seen presents a serious problem for man. Why? Because “all have sinned and fall short of the glory of God” (Romans 3:23). The Bible says that “the wickedness of man [is] great on the earth, and that every intent of the thoughts of [man’s] heart [is] only evil continually” (Genesis 6:5; cf. 8:21). In other words, mankind is wicked to the core; it is a heart issue. In fact, Jesus said, “That which proceeds out of the man, that is what defiles the man. For from within, out of the heart of men, proceed the evil thoughts, fornications, thefts, murders, adulteries, deeds of coveting and wickedness, as well as deceit, sensuality, envy, slander, pride and foolishness. All these evil things proceed from within and defile the man” (Mark 7:20-23). The problem is not that you’ve done a little wrong, and now you just have to try to do a little better. The problem is your heart is bad; it is corrupt; rotten. What you need is not a check-list of good deeds, as if you can bribe God with your stained works. Rather, what you need is a new heart, spiritually speaking. This, only God can do. Only God can make you clean. Only God can forgive your sins, thus allowing you to enter into fellowship and eternal life with Him. So what has He done to bring this about?
The Righteousness & Holiness of Jesus Christ
The answer is Jesus Christ. “For God so loved the world, that He gave His only [unique] Son, that whoever believes in Him shall not perish, but have eternal life” (John 3:16). Here we have the promise of the forgiveness of sins and the blessing of eternal life by faith in Jesus. How can this be? What has God done to make this so? The answer is summed up for us in these words: “He [God the Father] made Him [Jesus, the Son of God] who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him” (2 Corinthians 5:21). This verse speaks of a substitutionary sacrifice. First, it affirms that Jesus was/is without sin – He is spotless. Second, it affirms that man is sinful. Third, it affirms that He took the place of sinners, bearing their sin and the punishment for their sin on the cross. Lastly, it affirms that those who are found in Christ, through faith, become the righteousness of God. In summary, Jesus is the holy and righteous mediator between God and man (Acts 3:14; 1 Timothy 2:5). Remember, no evil dwells with God. Therefore, the only way that you can be reconciled to God, and so have eternal life, is to be found in the holy and righteous one, Jesus Christ, through faith. The Bible says, “And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved” (Acts 4:12).
The Command to Repent & Believe
So, where does this leave you? Well, as the Bible says, repent of your sins and believe in the good news – the gospel – which you have just heard (Mark 1:15; Acts 16:30-31; Romans 10:9, 13), the good news of salvation in and through Jesus Christ. To repent is to recognize the sinfulness of your sin, that it is a transgression of God’s holy Law (1 John 3:4), and therefore you turn from desiring the things that are contrary to God and His will, and you turn to God through faith in Jesus Christ. To believe in Jesus Christ is to truly be convinced of the things that you have just heard, and to rest in Christ alone for the forgiveness of your sins and reconciliation with God. If you repent and believe, you will be saved! May the good Lord grant you repentance and faith this day, and from this day on may you seek to live a life unto His glory.
Final Words of Encouragement
If you have a Bible at home, then I encourage you to pick it up and read it. However, it’s important to know that not all Bible translations are accurate or good. Some good Bible translations are the following: New American Standard Bible (NASB); English Standard Version (ESV); New King James Version (NKJV); King James Version (KJV); and the New International Version (NIV). A good place to start reading is Genesis 1-3, then read the Gospel according to John. Further, spend some time seeking the Lord in prayer, giving Him thanks and asking for His guidance as you read the Bible. Lastly, if you have believed in the gospel, then it is important for you to find a local church that is committed to the Bible and the gospel. May you be blessed and grow in the grace and knowledge of our Lord and Savior, Jesus Christ.
